Overview.

Cortex RTR broadband radio telemetry receiver is a complete telemetry receiver including RF
receivers, pre-D and post-D processing, demodulators, bit synchronizers and decoders. It is based on
the Cortex architecture, showing versatile features for all telemetry applications. It provides two TCP/IP
sockets interfaces allowing integration in any system type, an easy-to-use GUI for configuration and
monitoring. It is a compact design housed in a single 4U unit and relying on PCI express bus

architecture.

The receiver is mainly built around several kind of PCI-Express board:

The Tuner Boad:

Tuner-S, allowing receive only S band signals.

Tuner-IRIG, allowing receive S/L/Cif/P band signals.

The C-Band board:

MultiBand-C, coupled with the Tuner-S board, allowing receive only restricted C-Europe band
signals.

Converter-C, coupled with the Tuner-IRIG board, allowing receive C-full band signals.

The Signal Processing board:

ADP3, allowing the Digitization, Demodulation, Decoding, DATA transmission....etc.
Many analog I/O access are provided (AGC outputs, tape in/out, AM demodulator out, 70 MHz
interface...) for the purpose of test monitoring and interfacing with external equipment.
In case of IF recording, a direct 70MHz signal can be applied to the receiver through the last stage of
the RF converter taking advantage of the filter bank.
The auxiliary input is used when an external signal has to be applied to the Cortex RTR:

IRIG carrier for playback.

PCM signal to be applied to the bit synchronizer (Independent user).

Demodulated signals from another Cortex RTR to compute 4 channel post D combining.
